BACKGROUND TECHNICAL FIELD

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a method and a device for multi-connection or multi-TRP transmission.

RELATED ART

During the formulation of the 3rd Generation Partnership Project (3GPP) Release 16, the mobility enhancement in New Radio (NR) and Long Term Evolution (LTE) has been accomplished for the purpose of reducing data transmission interruptions within handover as well as enhancing the robustness of handover. And for the Work Item (WI) of enhanced Dual Connection and Carrier Aggregation (eDCCA) and Mobility Enhancement, discussions are focused on Conditional PSCell (i.e., Primary SCG Cell) Addition/Change (CPAC) but the conclusion has not yet been reached due to the time limit. At the RAN 86 conference a WI of “further enhancement on Multi-Radio Dual-Connectivity (MR-DC)” in Release 17 has been approved to promote studies on CPAC and provide support to more scenarios not mentioned in Release 16.

For Beam Management (BM), the 3GPP introduces a mechanism of Beam Failure Recovery (BFR) for the Special Cell (SpCell) in Release 15 (R15), and then a BFR mechanism for Secondary Cell (SCell) is introduced in R16. With the BFR mechanism, the Radio Link Failure (RLF) in any higher layer can be avoided. A Work Item (WI) of “Further enhancements on Multiple Input Multiple Output (MIMO) for NR” has been decided at the 3GPP Radio Access Network (RAN) #80 conference to be conducted for enhancing the Multiple-Transmitter-and Receiver-Point (multi-TRP) BFR mechanism.

SUMMARY

Both a Master Node (MN) and a Secondary Node (SN) can initiate a Conditional PSCell Change (CPC), for which the Execution Condition is up to either the MN or the SN to decide. A User Equipment (UE) maintains two measurement configuration storage spaces respectively associated with the MN and the SN. Due to the time limit, the 3GPP Release 16 is designed only targeting CPC initiated by the SN and not joined by the MN. How to select a corresponding measurement configuration when both the SN and MN are configuring for CPC still remains unsolved.

To address the above problem, the present application provides a solution. In view of the description of the above problem, the scenario of Terrestrial Network (TN) has been taken as an example; the present application is also applicable to scenarios such as Non-Terrestrial Network (NTN), and V2X, where technical effects similar to TN scenario can be achieved. Additionally, the adoption of a unified solution for various scenarios contributes to the reduction of hardcore complexity and costs.

The BFR mechanism in the current protocols is cell-level, when it comes to multi-TRP BFR, a practicable scheme is to configure an independent BFR procedure per TRP in a cell, which is to define a TRP-level BFR, therefore, when the UE simultaneously supports cell-level BFR and TRP-level BFR, the combined designing of cell-level BFR and TRP-level BFR shall be enhanced.

To address the above problem, the present application provides a solution. The description above only took Massive Multiple Input Multiple Output (MIMO) and beam-based communication scenarios for example; this disclosure is also applicable to scenarios with Long Term Evolution (LTE) multi-antenna system, where technical effects similar to those in Massive MIMO and beam-based communications can be achieved. Additionally, the adoption of a unified solution for various scenarios contributes to the reduction of hardcore complexity and costs.

In FIG. 3 , the radio protocol architecture for a control plane 300 is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively.

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to the present application, as shown in FIG. 4 . FIG. 4 is a block diagram of a first communication device 450 and a second communication device 410 in communication with each other in an access network.

The first communication device 450 comprises a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter/receiver 454 and an antenna 452.

The second communication device 410 comprises a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter/receiver 418 and an antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, a higher layer packet from a core network is provided to the controller/processor 475. The controller/processor 475 provides functions of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resource allocation of the first communication device 450 based on various priorities. The controller/processor 475 is also in charge of HARQ operation, a retransmission of a lost packet and a signaling to the first communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (i.e., PHY). The transmitting processor 416 performs coding and interleaving so as to ensure a Forward Error Correction (FEC) at the second communication device 410 side and the mapping of signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, and M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, which includes precoding based on codebook and precoding based on non-codebook, and beamforming processing on encoded and modulated signals to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multicarrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multicarrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream, which is later provided to different antennas 420.

In a transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, and converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs reception analog precoding/beamforming on a baseband multicarrier symbol stream provided by the receiver 454. The receiving processor 456 converts the processed baseband multicarrier symbol stream from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any first communication device 450-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted by the second communication device 410 on the physical channel. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 provides functions of the L2 layer. The controller/processor 459 can be associated with a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer. Or various control signals can be provided to the L3 for processing.

In a transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the second communication device 410 described in the transmission from the second communication node 410 to the first communication node 450, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resource allocation so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for a retransmission of a lost packet, and a signaling to the second communication device 410. The transmitting processor 468 performs modulation and mapping, as well as channel coding, and the multi-antenna transmitting processor 457 performs digital multi-antenna spatial precoding, including precoding based on codebook and precoding based on non-codebook, and beamforming. The transmitting processor 468 then modulates generated spatial streams into multicarrier/single-carrier symbol streams. The modulated symbol streams, after being subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457, are provided from the transmitter 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In a transmission from the first communication device 450 to the second communication device 410, the function of the second communication device 410 is similar to the receiving function of the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be associated with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decrypting, header decompression, control signal processing so as to recover a higher-layer packet from the first communication device (UE) 450.
